Secrets

 * 1) The northern area has two cages with switches. Press both, then enter the nukage with the partial invisibility. A door will open to the east, allowing access to a lift which takes you to a path leading to a door to four shotgun guys, and a backpack (four on multiplayer). (sector 99)
 * 2) The southern end of the blue corridor containing the red door has a lift to the west leading to a room with three pillars. There is a switch behind the middle one - pressing it opens a door in the area to the north, allowing access to a room with a rocket launcher (the platform lowers on pressing) and a box of rockets. (sector 102)
 * 3) In the south is a lava corridor. Part-way along is a secret door (marked with a gargoyle switch) leading to a computer area map. (sector 289)
 * 4) The western part of the east-west nukage corridor in the south has a path to the north. Part-way along is a lift dropping you down to a locked door. Grab the energy cell pack to the west - you will drop down to a room with two imps, two boxes of bullets, a medikit, a plasma rifle, and a partial invisibility. Entering this area opens up the locked door - behind it is a switch. There are two secrets here. (sector 259)
 * 5) See #5. (sector 257)
 * 6) The switch in the room opposite #5 lowers a pillar in the nukage north of #2 containing a megaarmor. (sector 263)
 * 7) The nukage area containing #6 also has a pillar containing a supercharge. This is lowered by a switch at the end of the western arm of the octagonal lift in the east. (sector 278)
 * 8) The path surrounding the exit leading to the yellow key area has a secret door to the east, leading to an invulnerability. (sector 291)
